Figure 2: Probability density function of randomly generated regulatory scores and the approximated fit by the stretched exponentials. The solid line denotes the empirical probability density function of regulatory scores obtained by the LIMMA-based method based on randomly generated condition clusterings, while the dotted line denotes the stretched exponentials (7) with ℎmax=0.127, 𝑏𝑟=0.024, 𝑏𝑙=0.083, 𝑐𝑟=2.45, 𝑐𝑙=1.70, and 𝑥max=−0.050.
